VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 234,238, dated November 9, 1880.

Application filed September 11, 1880. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM P. BUTLER, a citizen of the United States, residing at C-hicago, in the county of Cook and State of Illinois, have invented new and useful Improvementsin Vapor-Burners, of which the following is a specification.

The nature of my present invention relates to vapor-burners.

The chief objection to vapor-burners as heretofore constructed is, that the plate does not in cold weather convey sufficient heat to sustain the vaporization of the oil 5 also, that side or rear drafts of air are apt to disturb and extinguish the light, and also that the vapor issues irregularly and in sudden jets.

The object of myinvention is to remedy these defects; and it consists, first, in a vapor-burner comprising a metal burner-body formed integral with a curved deflecting-plate at that end of the burner which connects with the supplytnbe, a needle-valve passing into the burner at the opposite end thereof, and a protectingshield forming also side and top walls of a mixing-chamber between the gas-discharge orifice of the burner and the deflector, substantially as hereinafter set forth; second, in a vapor-burner, the combination, with the cast ing or body of the burner, having an oil and vapor channel leading from the supply-tube to the gas-discharge orifice, of the nipple rising from said channel, an adjustable shield, constituting, also, the side walls of the mixingchamber and fitted to the nipple, and a cap fitted upon said nipple to hold the shield in place, and having an expansion-chamber communicating with the oil and vapor channel through the medium of its nipple, all as hereinafter more fully described; third, in a vaporbnrner, the combination, with the body of the burner having an oil and vapor channel, of the nipple closed by a cap having a length greater than the height of the nipple, and formed with an expansion-chamber. communicating with the oil and vapor channel through the medium of its nipple, all as more fully hereinafter set forth.

In the drawings, Figure 1 is a perspective view of a vapor-burner constructed in accordance with my invention. Fig. 2 is a central longitudinal section thereof, taken on a vertical plane. Fig. 3 is a top or plan view with the adjustable lateral or shield and the screwcap, which secures the same in place, removed from the burner. Fig. 4 is a perspective view of the adjustable lateral or shield with its cap removed. Fig. 5 is a view of the top plate of the shield detached. Fig. 6 represents the top plate and sides of the shield formed in one piece.

Referring by letter to the accompanying drawings, A designates the burner, which 0011- sists of a metal casting having at one end a screw-threaded socket, to, for connecting the burner with an ordinary packing or supply tube, B, and having at its opposite end an internally screw-threaded hollow arm, a, in which the screw-threadcd stem of a needlevalve, 0, is adjusted.

The burner is provided with a screw-threaded nipple, D, arranged at a point intermediate of its two ends, above mentioned, and it is also formed with an oil and vapor chamber or channel, 0, through which communication is established between the packing-tube and the nipple, and also a passage formed to the gas-discharge orifice.

The burner is provided upon its under side with an arm, D, to which is secured a dripcup, E, wherein the initiatory supply of oil is burned for the purpose of generating a supply of gas before the needle-valve is opened.

F designates the curved deflecting-plate against which the gas-jet impinges, so as to spread the illuminating-flame. This curved deflector is made integral with the casting which composes the burner A, so that when the deflector becomes heated by the flame heat therefrom will be conducted to the walls of the oil and vapor channel 0, for the purpose of vaporizing the oils more readily than if the said deflector were formed in a separate piece from the burner. This deflector is arranged adjacent that end of the burner into which the supply-pipe fits, thus making but a short distance between the channel and the deflector, and thereby insuring the vaporization of the oil. The needle-valve which regulates the flow of vapor from the oil and vapor channel passes between the nipple and the said channel and seats in a valve-seat, d, at the vapor-discharge outlet d. The shield or lateral G, which is formed and applied to the burner so as to provide, also, for the side walls of a mixing chamber or passage, g, in which the vapor issuing from the oil and vapor channel is mingled with air before burning, is fitted to the nipple, and at such perforated end rests upon a seat, h, on the burner. This shield or lateral is provided with side flanges, H H, which diverge from each other in the general direction of the curved deflectingplate, so that when the shield is secured to the burner their inner faces embrace the sides of that portion,f, of the burner which is in the nature of an approximately-horizontal lower extension of the deflecting-plate. As shown in Figs. 2 and 4, the sides H of the shield or lateral are connected by a plate, 1, formed with a hole, 1', the walls of which tit to the nipple when the shield is connected with the burner, and the top plate, H, of the shield is made with a slot, 11, so that when said top plate is fitted upon the nipple it may be adjusted, in order to control the burning and shape the flame, widening or contracting the space or opening between the top plate and the curved deflecting-plate. If desired, however, the top plate may be formed with the shield and take the place of the plate 1', whereby the entire shield will be rendered adjustable, as shown in Fig. 6. A suitable space is left between the shield and thedeflecting-plate, as herein shown, in order to admit air to the mixing-chain her from below. The shield effectively protects the mixing-chamber and the burner from wind or drafts of air which would otherwise tend to produce a deviation in the course of the vapor on its way to the deflector, and also tend to cover the burner. The shield. after being fitted to the burner, as herein shown, is secured in place by a cylindrical cap, K, which is screw-threaded interiorly and adapted to be screwed down upon the nipple, so that its lower end will bear upon the shield and firmly hold the top end of said shield against the seat provided on the burner at or above the base of its nipple. The length of this cap is greater than the height of the nipple, so that when secured in place it affords an expansion-chainber, K, in which a suflicient quantity of gas will be stored during the vaporization of the oil to regulate the pressure and insure an equable flow of gas through the discharge-orifice of the burner, the gas in said expansion-chamber, which passes by the outlet and into the same, forming an elastic cushion therein.

My burner thus constructed is simple,cheap, and efi"ective, and will be found to work perfectly under all circumstances.

The metallic tube leading the oil to the burner will be filled with silica, for the purpose of regulating the flow of oil and preventing the reflux of gas. I have discovered that the packing generally used in this connection in vaporburners is either combustible or liable to corrosion by the action of the acids in the oils, and that silica of about the size of No. 6 emery overcomes such defects.

Heretofore a vapor-burner body has been formed in one piece with a deflector-plate on that side of the burner which connects with the feed-tube. and such, broadly, I disclaim. Further, a vapor-burner has been constructed with a separate curved deflector-plate, a shield or protector, and an adjustable needle-valve, and such, broadly, I disclaim.

\Vhat I claim is- 1. In com bination with avapor-burner formed in a single piece, with a curved deflecting-plate at the side of the burner which connects with the feed-supply tube, an adjustable needlevalve arranged in the opposite side of said burner and a horizontally-adjustable shield having side flanges and a top wall, forming a mixing-chamber, substantially as described.

2. In a vapor-burner, the combination, with the casting or body of the burner having an oil and vapor channel leading from the supply-tube to the gas-discharge orifice, of the nipple rising from said channel, an adjustable shield constituting, also, the side walls of the mixing-chamber and fitted to the nipple, and a cap fitted upon said nipple to hold the shield in place, and having an expansion-chamber communicating with the oil and vapor channel through the medium of its nipple, substantially as herein described.

3. In a vapor-burner, the combination,with the body of the burner having an oil and vapor channel, of the nipple closed by a cap having a length greater than the height of the nipple and formed with an expansion-chamber communicating with the oil and vapor channel through the medium of its nipple, substantially as set forth.

4. The combination, with a vapor-burner body formed integral with a curved deflectingplate at the side, where the body connects with the feed-tube, of a protecting-shield having a horizontal top and vertical side walls forming a mixing-chamber, said top plate of the shield being capable of horizontal adjustment for regulating its position with respect to the deflecting-plate, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
